$40 Plug-In Impeller Lets SmartPhone Work as Wind Reader

Gear Report by Kip Staton
Shooters in the market for an accurate anemometer that doesn’t break the bank need to take a hard look at the WeatherFlow Wind Meter, which retails on Amazon.com for just $39.95. Even though it is inexpensive, owner reviews have been overwhelmingly postive (so long as the software is compatible with your device). One Amazon reviewer says the WeatherFlow measures wind velocity as accurately as his expensive Kestrel.

A big part of the reason the WeatherFlow Wind Meter is so inexpensive is that you’ve probably already got the brains of the system in your pocket. Yes, it connects to and communicates with any standard smartphone or tablet, in either iOS or Android flavors. Users simply download the free WeatherFlow Wind Meter app to their smart device, insert the anemometer into the headphone jack, and can immediately start measuring the wind.

Of course, the first question any serious shooter will ask is “How accurate is this thing?” Pretty dang accurate, as it turns out. The device was calibrated by the University of Florida’s Aerospace Engineering Department, and the unique design allows it to consistently report to within a half a percentage point of the true wind value, even if the breeze is up to 15 degrees off-axis to the meter.

Wind speeds are measurable from as slow as two miles per hour to as high as 125 MPH. The Wind Meter outputs average, lull, and gusts windspeed data to your phone, with velocities indicated in 0.1 MPH increments. Furthermore, a hard-sided protective case is included for safe transportation.

Naturally, since the WeatherFlow Wind Meter is App-based, it’s connectable to a variety of social media websites and distribution sources. This makes saving and sharing information about climate conditions a breeze.
